Australian Prime Minister Malcom Turnbull has been campaigning hard ahead of a general election that’s too close to call.

Australians will vote on Saturday, and the million dollar question is whether they’ll back the 61-year-old Liberal party leader or change prime minister for the fifth time in as many years.

His main rival is Labour leader Bill Shorten. The 49 year-old is pledging more funding for schools and hospitals.

But Turnbull, who called the early election in the hope of cementing his majority in parliament, is waving the Brexit card — saying that with the current market turbulences threatening the global economy, Australia needs stability above all.

“This is not a time to make a protest vote. This is a time to treat your vote as though that is the single vote that will determine the next government,” he told reporters in Sydney.
